FIELD OF THE INVENTION

This invention is in the field of pharmaceutical agents and specificallyrelates to compounds, compositions, uses and methods for treatinginflammation-related disorders, including pain.

BACKGROUND OF THE INVENTION

More than two million people in the United States alone areincapacitated by chronic pain on any given day (T. M. Jessell & D. D.Kelly, Pain and Analgesia in Principles of Neural Science, 3^(rd)edition (E. R. Kandel, J. H. Schwartz, T. M. Jessell, editors, (1991)).Unfortunately, current treatments for pain are only partially effective,and many cause life-style altering, debilitating, and/or dangerous sideeffects. For example, non-steroidal anti-inflammatory drugs (“NSAIDs”)such as aspirin, ibuprofen, and indomethacin are moderately effectiveagainst inflammatory pain but they are also renally toxic, and highdoses tend to cause gastrointestinal irritation, ulceration, bleeding,increased cardiovascular risk, and confusion. Patients treated withopioids frequently experience confusion and constipation, and long-termopioid use is associated with tolerance and dependence. Localanesthetics such as lidocaine and mixelitine simultaneously inhibit painand cause loss of normal sensation. In addition, when used systemically,local anesthetics are associated with adverse cardiovascular effects.Thus, there is currently an unmet need in the treatment of chronic pain.

Pain is a perception based on signals received from the environment andtransmitted and interpreted by the nervous system (for review, see M. J.Millan, Prog. Neurobiol. 57:1-164 (1999)). Noxious stimuli such as heatand touch cause specialized sensory receptors in the skin to sendsignals to the central nervous system (“CNS”). This process is callednociception, and the peripheral sensory neurons that mediate it arenociceptors. Depending on the strength of the signal from thenociceptor(s) and the abstraction and elaboration of that signal by theCNS, a person may or may not experience a noxious stimulus as painful.When one's perception of pain is properly calibrated to the intensity ofthe stimulus, pain serves its intended protective function. However,certain types of tissue damage cause a phenomenon, known as hyperalgesiaor pronociception, in which relatively innocuous stimuli are perceivedas intensely painful because the person's pain thresholds have beenlowered. Both inflammation and nerve damage can induce hyperalgesia.Thus, persons afflicted with inflammatory conditions, such as sunburn,osteoarthritis, colitis, carditis, dermatitis, myositis, neuritis,inflammatory bowel disease, collagen vascular diseases (which includerheumatoid arthritis and lupus) and the like, often experience enhancedsensations of pain. Similarly, trauma, surgery, amputation, abscess,causalgia, collagen vascular diseases, demyelinating diseases,trigeminal neuralgia, cancer, chronic alcoholism, stroke, thalamic painsyndrome, diabetes, herpes infections, acquired immune deficiencysyndrome (“AIDS”), toxins and chemotherapy cause nerve injuries thatresult in excessive pain.

As the mechanisms by which nociceptors transduce external signals undernormal and hyperalgesic conditions become better understood, processesimplicated in hyperalgesia can be targeted to inhibit the lowering ofthe pain threshold and thereby lessen the amount of pain experienced.

Bradykinin (BK) and the related peptide, kallidin (Lys-BK) mediate thephysiological actions of kinins on the cardiovascular and renal systems.However, the active peptides, BK and kallidin, are quickly degraded bypeptidases in the plasma and other biological fluids and by thosereleased from a variety of cells, so that the half-life of BK in plasmais reported to be approximately 17 seconds (1). BK and kallidin arerapidly metabolized in the body by carboxypeptidase N, which removes thecarboxyterminal arginine residue to generate des-Arg BK or des-Argkallidin. Des-Arg-kallidin is among the predominant kinins in man andmediate the pathophysiological actions of kinins in man. In addition tobeing a very potent proinflammatory peptide, des-Arg-BK ordes-Arg-kallidin is known to induce vasodilation, vascular permeability,and bronchoconstriction (for review, see Regoli and Barabe,Pharmacological Rev, 32(1):1-46 (1980)). In addition, des-Arg-BK anddes-Arg-kallidin appear to be particularly important mediators ofinflammation and inflammatory pain as well as being involved in themaintenance thereof. There is also a considerable body of evidenceimplicating the overproduction of des-Arg-kallidin in conditions inwhich pain is a prominent feature such as septic shock, arthritis,angina, and migraine.

The membrane receptors that mediate the pleiotropic actions of kininsare of two distinct classes, designated B1 and B2. Both classes ofreceptors have been cloned and sequenced from a variety of species,including man (Menke, et al, J. Biol. Chem., 269:21583-21586 (1994);Hess et al, Biochem. Biophys. Res. Commun., 184:260-268 (1992)). Theyare typical G protein coupled receptors having seven putative membranespanning regions. In various tissues, BK receptors are coupled to everyknown second messenger. B2 receptors, which have a higher affinity forBK, appear to be the most prevalent form of bradykinin receptor.Essentially all normal physiological responses and manypathophysiological responses to bradykinin are mediated by B2 receptors.

B1 receptors, on the other hand, have a higher affinity for des-Arg-BKcompared with BK, whereas des-Arg-BK is inactive at B2 receptors. Inaddition, B1 receptors are not normally expressed in most tissues. Theirexpression is induced upon injury or tissue damage as well as in certainkinds of chronic inflammation or systemic insult (Marceau, F. et al.,Immunopharmacology, 30:1-26 (1995)). Furthermore, responses mediated byB1 receptors are upregulated from a null level following administrationof bacterial lipopolysaccharide (LPS) or inflammatory cytokines inrabbits, rats, and pigs.

The pain-inducing properties of kinins coupled with the inducibleexpression of B1 receptors make the B1 receptor an interesting target inthe development of antiinflammatory, antinociceptive, antihyperalgesicand analgesic agents that may be directed specifically at injuredtissues with minimal actions in normal tissues.

Clearly, there is a need for new, safe and effective treatments forinflammation and pain. Such agents are provided in the presentinvention.

DEFINITIONS

The phrase “therapeutically-effective” is intended to qualify the amountof each agent, which will achieve the goal of improvement in disorderseverity and the frequency of incidence over treatment of each agent byitself, while avoiding adverse side effects typically associated withalternative therapies. For example, effective pain therapeutic agentsrelieve the pain sensation of the patient. Alternatively, effectivetherapeutic agents for the treatment of inflammation minimize the damagefrom the inflammation, and the like.

The term “treatment” includes therapeutic treatment as well asprophylactic treatment (either preventing the onset of disordersaltogether or delaying the onset of a preclinically evident stage ofdisorders in individuals).

The term “H” denotes a single hydrogen atom. This radical may beattached, for example, to an oxygen atom to form a hydroxyl radical.

Where the term “alkyl” is used, either alone or within other terms suchas “haloalkyl”, “cyanoalkyl” and “alkylamino”, it embraces linear orbranched radicals having one to about twenty carbon atoms or,preferably, one to about twelve carbon atoms, or as otherwise indicated.More preferred alkyl radicals are “lower alkyl” radicals having one toabout six carbon atoms. Examples of such radicals include methyl, ethyl,n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, pentyl,iso-amyl, hexyl and the like. Even more preferred are lower alkylradicals having one to four carbon atoms. The term “alkylenyl” embracesbridging divalent alkyl radicals such as methylenyl and ethyleneyl.

The term “alkenyl” embraces linear or branched radicals having at leastone carbon-carbon double bond of two to about twenty carbon atoms or,preferably, two to about twelve carbon atoms, or as otherwise indicated.More preferred alkenyl radicals are “lower alkenyl” radicals having twoto about four carbon atoms. Examples of alkenyl radicals includeethenyl, 2-propenyl, allyl, butenyl and 4-methylbutenyl. The terms“alkenyl” and “lower alkenyl”, embrace radicals having “cis” and “trans”orientations, or alternatively, “E” and “Z” orientations.

The term “alkynyl” embraces linear or branched radicals having at leastone carbon-carbon triple bond of two to about twenty carbon atoms or,preferably, two to about twelve carbon atoms, or as otherwise indicated.More preferred alkynyl radicals are “lower alkynyl” radicals having twoto about four carbon atoms. Examples of alkynyl radicals includeethynyl, 2-propynyl, and 4-methylbutynyl.

The term “halo” means halogens such as fluorine, chlorine, bromine oriodine atoms.

The term “haloalkyl” embraces radicals wherein any one or more of thealkyl carbon atoms is substituted with halo as defined above.Specifically embraced are monohaloalkyl, dihaloalkyl and polyhaloalkylradicals including perhaloalkyl. A monohaloalkyl radical, for oneexample, may have either an iodo, bromo, chloro or fluoro atom withinthe radical. Dihalo and polyhaloalkyl radicals may have two or more ofthe same halo atoms or a combination of different halo radicals. “Lowerhaloalkyl” embraces radicals having 1-6 carbon atoms. Even morepreferred are lower haloalkyl radicals having one to three carbon atoms.Examples of haloalkyl radicals include fluoromethyl, difluoromethyl,trifluoromethyl, chloromethyl, dichloromethyl, trichloromethyl,pentafluoroethyl, heptafluoropropyl, difluorochloromethyl,dichlorofluoromethyl, difluoroethyl, difluoropropyl, dichloroethyl anddichloropropyl. “Perfluoroalkyl” means alkyl radicals having allhydrogen atoms replaced with fluoro atoms.

The β-amino acids 1 are commercially availableor may be prepared by literature methods. Similarly, substituted amine 2are either commercially available, can be prepared via literaturemethods, or may be prepared following literature methods described foranalogous compounds. Some of these methods are illustrated in thesubsequent schemes. Alternatively, substituted amide 3 is anintermediate to the compounds of Formula I. Protective groups employedin compounds 3 can be removed to provide deprotected compounds offormula I.

The β-amino acids 1 are commercially available or may be prepared byliterature methods. Similarly, substituted amine 3 are eithercommercially available, can be prepared via literature methods, or maybe prepared following literature methods described for analogouscompounds. Some of these methods are illustrated in the subsequentschemes. Alternatively, bicyclic-ring-substituted amide 5 is anintermediate to the compounds of Formula II. Protective groups employedin compounds 5 can be removed to provide deprotected compounds ofFormula II.

Compounds of Formula III may be prepared in a convergent manner asdescribed in Scheme 3. β-phenylalanine derivatives 6 are coupled withthe substituted chroman 7 using standard peptide coupling conditions,such as with HOBT EDC, and DIEA in a solvent, such as CH₂Cl₂, andreacted at RT, to afford the chroman-substituted amide 8.

Some ofthese methods are illustrated in the subsequent schemes. Alternatively,bicyclic-ring-substituted amide 8 is an intermediate to the compounds ofFormula II. Protective groups employed in compounds 8 can be removed toprovide deprotected compounds of Formula III.

Cyano substituted bicylic amines 13 may be prepared in a convergentmanner as described in Scheme 4. 5-Oxo-5,6,7,8-tetrahydro-naphth-2-ylcarbonitrile 9 is reduced, such as with NaBH₄, in a solvent such as THFand MeOH at a temperature between about 0° C. and about 30° C.,preferably about RT, to form the5-hydroxy-5,6,7,8-tetrahydro-naphth-2-yl carbonitrile 10. The alcohol 10is converted to the halide 11, such as the chloride, such as bytreatment with SOCl₂ in a solvent such as CH₂Cl₂, at a temperaturebetween about 0° C. and about 30° C., preferably about RT. The5-chloro-5,6,7,8-tetrahydro-naphth-2-yl carbonitrile 11 is treated withNaN₃ in a solvent such as dry DMF, at a temperature above RT, preferablyabove about 50° C., even more preferably at about 75° C., to form the5-azido-5,6,7,8-tetrahydro-naphth-2-yl carbonitrile 12. The azide ishydrogenated, such as with H₂ in the presence of a catalyst, such asPd/C, in the presence of solvent, such as in EtOAc, to form the amine13. These steps can be used to form analogous cyano substituted bicylicamines.

5-Oxo-5,6,7,8-tetrahydro-naphth-2-yl carbonitrile 9 can be prepared fromcorresponding alcohols by the methods described in Scheme 5.6-Hydroxy-3,4-dihydro-2H-naphthalen-1-one 14 is converted to thetriflate 15 by treatment with trifluoro-methanesulfonic anhydride in asolvent such as CH₂Cl₂, in the presence of base, such as NMM, and DMAP,and at a temperature below RT, preferably at a temperature at about 0°C. The triflate 15 is reacted with KCN in the presence of PPh₃ and(PPh₃)₂NiBr₂ in a solvent such as degassed CH₃CN, a temperature aboveRT, preferably above about 50° C., even more preferably at about 60° C.,to form the cyano compound 9. These steps can be used to form analogousoxo substituted bicylic carbonitriles.

Compounds of Formula I may be prepared in a convergent manner asdescribed in Scheme 6. Cyano chromans 16 are reduced, such as with Raneynickel in the presence of formic acid, a temperature above RT,preferably above about 75° C., even more preferably at about 100° C., toform the formyl compounds 17. Reductive amination of the formylcompounds 17, such as with NaBH(OAc)₃ and an amine, provides theaminomethyl compounds 18 (where R^(z) is H or alkyl or together with theamine forms a cyclic compound). The compounds can be isolated as a saltor as the free base. These steps can be used to form analogouscompounds.

Compounds of Formula I may be prepared in a convergent manner asdescribed in Scheme 7. Cyano chromans 16 are reduced, such as withhydrogen in the presence of a catalyst such as Pd(OH)₂, in a solvent,such as MeOH, to form the corresponding aminomethyl compounds 19.

Amino compounds 22 are prepared from the corresponding ketones 20 by themethod described in Scheme 8. Treatment of the ketones 20 withhydroxylamine in a solvent such as NaOAc, at a temperature above RT,preferably above about 75° C., even more preferably at reflux, providesthe oxime 21. Hydrogenation of the oxime 21, such as in the presence ofa catalyst such as Pd/C, provides the amine 22.

Compounds of Formula I may be prepared in a convergent manner asdescribed in Scheme 9. Esters 23 are reduced to the correspondingalcohols 24, such as in the presence of LiBH₄, at a temperature aboveRT, preferably above about 50° C. Derivatization to the mesylate andtreatment with an amine provides compounds 25.

In addition compounds of Formula I can be prepared in diastereomericallypure forms using the method described in Scheme 10. Keto-trifalates15a-c are subjected to Pd mediated carbonylation in a mixture of DMSOand MeOH to afford the ketoesters 26a-c. Enantioselective reduction ofthe ketone moieties, e.g. using either the CBS (E. J. Corey et al., J.Am. Chem. Soc. 109, 5551 (1987)) or Noyori. (T. Noyori, et al., J. Am.Chem. Soc., 1995, 117, 2675-2676) protocols affords either enantiomer ofthe alcohols with an enantiomeric excess of >99%. Either the R⁸ or Senantiomer of the amine may be prepared by using either of theenantioselective reduction protocols. Azidation of the resultingsecondary alcohol using a method described by Thompson et al. (Journalof Org. Chem. (1993), 58(22), 5886-8.) and LAH reduction affords theenantiopure amino alcohols 29a-c in high yield.

The resulting amino alcohols further elaborated into compounds ofFormula I as depicted in Scheme 11, similar to that described in Scheme6.

Analogs of compounds of Formula II may be prepared as illustrated inSchemes 12-14. Following Boc protection, amino alcohol 29a is convertedto its methyl ketone 37 by the three step procedure depicted in scheme12. Protected 1-amino-6-hydroxymethyl-1,2,3,4-tetrahydro-naphthalene 34is oxidized, such as with MnO₂ in an organic solvent, such as CH₂Cl₂,preferably at a temperature of about RT, to form the aldehyde 35. Thealdehyde is alkylated, such as with a Grignard reagent in a solvent suchas THF, at a temperature initially below RT, preferably about −30° C.and more preferably at about −78° C., then at about RT, to form thealcohol 36. The alcohol 36 is oxidized, such as with MnO₂ as previouslydescribed, to form the protected ketone 37. The resulting ketone 37 isdeprotected such as with HCl, and converted to compound 41 similar tothe method described in Scheme 11.

Ether linked analogs such as 45, are prepared by the convergentsynthesis depicted in scheme 13. The 6-hydroxy-1-tetralone 14 is reactedwith an amine, such as N,N-dimethylethanolamine, preferably in thepresence of PPh₃ and DEAD at a temperature preferably between about 0°C. and about RT to form the6-(2-dimethylamino-ethoxy)-3,4-dihydro-2H-naphthalen-1-one 42. the6-(2-dimethylamino-ethoxy)-3,4-dihydro-2H-naphthalen-1-one 42 is reactedwith hydroxylamine hydrochloride and base, such as Et₃N. The reaction isheated above RT, preferably at reflux to form the oxime 43.Hydrogenation of the oxime 43, such as with Pd/C and H₂ provides theamine 44 which can be coupled with the appropriate acid to form thedesired compound 45.

β-Phenethyl amine and γ-phenpropyl amine derivatives of compounds ofFormula II may be prepared by the methods illustrated in Scheme 14. The6-hydroxy-1-tetralone was protected with triflic anhydride and thetemperature was preferably maintained between 0 C and RT, to formtriflate 15. Treatment of the triflate 15 with(R)-2-methyl-CBS-oxazaborolidine and BMS and trifluoro-methanesulfonicacid at a temperature between 0 C and RT, provides the alcohol 46. Thealcohol 46 was converted to the azide by addition of DBU and dppa, at atemperature between 0 C and RT. Addition of PPh₃ to the azide 47provides the amine 48, which can be coupled, as described above, withthe appropriate acid to form amide 49. Reaction with the amide 49palladium(II) acetate, dppf, base (e.g. Et₃N) and allyl alcohol, heatedto a temperature above RT, preferably between about 50° C. and about100° C., more preferably at about 80° C. provides the vinyl alcohol 50.Treatment of the 1-hydroxymethyl-vinyl compound 50 with methanesulfonylchloride provides Mesyl derivative 51, which upon treatment with anamine, such as pyrrolidine, provides the vinyl amine 52.

Following the protocols described above the tether length for all of theamino compounds of Formulas I and II may be varied from 1-4 carbons. Thealcohol 29b can be converted to the carbonitrile 52 such as withtreatment with P(Ph)₃, DEAD and acetone cyanohydrin. The nitrile 52 canbe coupled with the acid, such as with HATU, EDC and DIEA. The(7-cyanomethyl-4-chroman 53 is hydrogenated, such as with palladiumcatalyst in an alcohol, e.g. MeOH, to form the alkyl amine 54 of thepresent invention. The alkyl amine can be substituted using standardmethods to make the substituted amines 55 (where R^(n) is alkyl,substituted alkyl, and the like).

Methods for preparing additional compounds of formulas I and II areillustrated in scheme 16. The cyano alcohol 56 can be treated with DMAP,base (e.g. NEt₃), and PBDPSCl to form the protected alcohol 57. Theprotected alcohol 56 is aminated, such as with Me₃Al, at a temperaturebelow RT and preferably at about 0 C, to yield the amidine 58. Formationof the 5,6,7,8-tetrahydro-quinazolone 60 is achieved such as by reactionof amidine 58 and 2-dimethylaminomethylene-cyclohexane-1,3-dione 59 at atemperature above RT, preferably above about 5° C. and more preferablyat about 80 C. 5,6,7,8-tetrahydro-quinazolone 60 is reduced such as withNaBH₄ to give the alcohol 61. The alcohol 61 is treated with DPPA andDBU to form the azide derivative which is reduced to form the amine 62.The amine 62 is deprotected, such as with TBAF to form the desiredintermediate 63.

Compounds of the invention 72 can be prepared as described in Scheme 18.The protected amino bicyclic compound 68 was treated with is alkylated,such as with vinyltributyltin in the presence of PPh₃, a base such asEt₃N and a palladium catalyst, e.g. Pd₂(dba)₃. The reaction ismaintained at a temperature above RT, preferably in a range betweenabout 5° C. and about 10° C., more preferably at about 8° C., morepreferably in a microwave. After deprotection, such as with TFA in thecase the amine is BOC protected, the free amine 69b can be coupled asdescribed above. Oxidation of the vinyl compound 70, such as with OsO4produces aldehyde 71. Reductive amination, such as with NaHB(OAc)₃ inthe presence of an amine provides compounds 72.

Compounds with alkylated sulfonamides 74 can be prepared as described inScheme 19. Treatment of the free sulfonamide 32 with iodoalkylcompounds, e.g. MeI, in the presence of base such as Na₂CO₃ provides thealkylated intermediate 73 which can be further treated as describedabove to provide compounds 74.

Alkylamine compounds can be prepared by the synthesis described inScheme 19. The amino-carbonitrile 75 is protected, such as with Boc₂O,to afford 76. Alkylation of the amine 76, such as treatment with base,e.g. NaH, and iodoaklyl, such as MeI, at a temperature preferably at RT,yields the alkylamine 77. Treatment of 77 with DIBALH and an acid suchas glacial HOAc provides the aldehyde 78. Reductive amination, similarto that previously described affords the amine 79, which upondeprotection yields the intermediate 80.

Alternatively, compounds with longer tethers are prepared by the methoddescribed in Scheme 20.(5-Amino-5,6,7,8-tetrahydro-naphthalen-2-yl)-methanol 81 is protected,such as with (Boc) 20 to provide 82. The protected amine 82 is oxidized,using methods described in other schemes above, to form the aldehyde 83.The cyano-vinyl compound 84 is prepared via treatment with diethylcyanophosphate and sodium bis(trimethylsilyl)amide at a temperaturebetween about −78° C. and RT. Deprotection yields the free amine 85which can be coupled as described above, to provide the intermediate 86.Reduction, such as with Pt catalyzed treatment with H₂ yields theaminopropyl compound 87 of the present invention.

Additional analogs of any of the templates in described in Schemes 1-20may be prepared using the procedures analogous to those described forabove and illustrated in the examples below. In addition elaboration ofall intermediates in the above schemes to compounds of Formula I may beaccomplished using known by those skilled in the arts of organic andmedicinal chemistry.

If one or more other functional groups, for example carboxy, hydroxy,amino, or mercapto, are or need to be protected in a compound ofFormulas I-VI and I′-VI′, because they should not take part in thereaction, these are such groups as are usually used in the synthesis ofpeptide compounds, and also of cephalosporins and penicillins, as wellas nucleic acid derivatives and sugars.

The protecting groups may already be present in precursors and shouldprotect the functional groups concerned against unwanted secondaryreactions, such as acylations, etherifications, esterifications,oxidations, solvolysis, and similar reactions. It is a characteristic ofprotecting groups that they lend themselves readily, i.e. withoutundesired secondary reactions, to removal, typically by solvolysis,reduction, photolysis or also by enzyme activity, for example underconditions analogous to physiological conditions, and that they are notpresent in the end-products. The specialist knows, or can easilyestablish, which protecting groups are suitable with the reactionsmentioned above and hereinafter.

The protection of such functional groups by such protecting groups, theprotecting groups themselves, and their removal reactions are describedfor example in standard reference works, such as J. F. W. McOmie,“Protective Groups in Organic Chemistry”, Plenum Press, London and NewYork 1973, in T. W. Greene, “Protective Groups in Organic Synthesis”,Wiley, New York 1981, in “The Peptides”; Volume 3 (editors: E. Gross andJ. Meienhofer), Academic Press, London and New York 1981, in “Methodender organischen Chemie” (Methods of organic chemistry), Houben Weyl, 4thedition, Volume 15/1, Georg Thieme Verlag, Stuttgart 1974, in H.-D.Jakubke and H. Jescheit, “Aminosäuren, Peptide, Proteine” (Amino acids,peptides, proteins), Verlag Chemie, Weinheim, Deerfield Beach, and Basel1982, and in Jochen Lehmann, “Chemie der Kohlenhydrate: Monosaccharideund Derivate” (Chemistry of carbohydrates: monosaccharides andderivatives), Georg Thieme Verlag, Stuttgart 1974.

In the additional process steps, carried out as desired, functionalgroups of the starting compounds which should not take part in thereaction may be present in unprotected form or may be protected forexample by one or more of the protecting groups mentioned above under“protecting groups”. The protecting groups are then wholly or partlyremoved according to one of the methods described there.

Salts of a compound of formula I with a salt-forming group may beprepared in a manner known per se. Acid addition salts of compounds offormula I may thus be obtained by treatment with an acid or with asuitable anion exchange reagent. A salt with two acid molecules (forexample a dihalogenide of a compound of formula I) may also be convertedinto a salt with one acid molecule per compound (for example amonohalogenide); this may be done by heating to a melt, or for exampleby heating as a solid under a high vacuum at elevated temperature, forexample from 130-170° C., one molecule of the acid being expelled permolecule of a compound of formula I.

Salts can usually be converted to free compounds, e.g. by treating withsuitable basic agents, for example with alkali metal carbonates, alkalimetal hydrogen carbonates, or alkali metal hydroxides, typicallypotassium carbonate or sodium hydroxide.

All process steps described here can be carried out under known reactionconditions, preferably under those specifically mentioned, in theabsence of or usually in the presence of solvents or diluents,preferably such as are inert to the reagents used and able to dissolvethese, in the absence or presence of catalysts, condensing agents orneutralizing agents, for example ion exchangers, typically cationexchangers, for example in the H⁺ form, depending on the type ofreaction and/or reactants at reduced, normal, or elevated temperature,for example in the range from about −100° C. to about 190° C.,preferably from about −80° C. to about 150° C., for example at about −80to about 60° C., at RT, at about −20 to about 40° C. or at the boilingpoint of the solvent used, under atmospheric pressure or in a closedvessel, where appropriate under pressure, and/or in an inert atmosphere,for example, under argon or nitrogen.

Salts may be present in all starting compounds and transients, if thesecontain salt-forming groups. Salts may also be present during thereaction of such compounds, provided the reaction is not therebydisturbed.

In certain cases, typically in hydrogenation processes, it is possibleto achieve stereoselective reactions, allowing for example easierrecovery of individual isomers.

The solvents from which those can be selected which are suitable for thereaction in question include, for example, H₂O, esters, typically loweralkyl-lower alkanoates, e.g. EtOAc, ethers, typically aliphatic ethers,e.g. Et₂O, or cyclic ethers, e.g. THF, liquid aromatic hydrocarbons,typically benzene or toluene, alcohols, typically MeOH, EtOH or1-propanol, IPA, nitriles, typically CH₃CN, halogenated hydrocarbons,typically CH₂Cl₂, acid amides, typically DMF, bases, typicallyheterocyclic nitrogen bases, e.g. pyridine, carboxylic acids, typicallylower alkanecarboxylic acids, e.g. HOAc, carboxylic acid anhydrides,typically lower alkane acid anhydrides, e.g. acetic anhydride, cyclic,linear, or branched hydrocarbons, typically cyclohexane, hexane, orisopentane, or mixtures of these solvents, e.g. aqueous solutions,unless otherwise stated in the description of the process.

The invention relates also to those forms of the process in which onestarts from a compound obtainable at any stage as a transient andcarries out the missing steps, or breaks off the process at any stage,or forms a starting material under the reaction conditions, or uses saidstarting material in the form of a reactive derivative or salt, orproduces a compound obtainable by means of the process according to theinvention and processes the said compound in situ. In the preferredembodiment, one starts from those starting materials which lead to thecompounds described above as preferred.

The compounds of Formula I-VI and I′-VI′, including their salts, arealso obtainable in the form of hydrates, or their crystals can includefor example the solvent used for crystallization (present as solvates).

New starting materials and/or intermediates, as well as processes forthe preparation thereof, are likewise the subject of this invention. Inthe preferred embodiment, such starting materials are used and reactionconditions so selected as to enable the preferred compounds to beobtained.

Starting materials of the invention, are known, are commerciallyavailable, or can be synthesized in analogy to or according to methodsthat are known in the art.

In the preparation of starting materials, existing functional groupswhich do not participate in the reaction should, if necessary, beprotected. Preferred protecting groups, their introduction and theirremoval are described above or in the examples.

All remaining starting materials are known, capable of being preparedaccording to known processes, or commercially obtainable; in particular,they can be prepared using processes as described in the examples.

N-[7-(2-Aminoethyl)-chroman-4-yl]-3-phenyl-3-(3-trifluoromethylbenzenesulfonylamino)-propionamideStep A. Preparation of (4-amino-chroman-7-yl)-acetonitrile

To a 125 mL flame dry 3-neck round bottom flask was added P(Ph)₃ (4.4 g,16.74 mmol) and THF (50 mL). After cooling to −20° C., DEAD (3.3 mL,16.74 mmol) was added dropwise via the addition funnel. After stirringfor 20 min at −20° C., (4-aminochroman-7-yl)-methanol (2.0 g, 11.16mmol) in THF (75 mL) was added dropwise via the addition funnel. It wasstirred for another 30 min. acetone cyanohydrin (3.1 mL, 33.48 mmol) wasthen added dropwise via the addition funnel. The resulting mixture waswarmed to RT and stirred for 18 h. Solvent was evaporated in vacuo. Theresidue was purified by chromatography on silica gel. Elution withCH₂Cl₂:MeOH mixture (95:5) gave final compound. MS m/z: 189.12 (M+H).Calc'd. for C₁₁H₂₂N₂O-188.23.

Biological Testing Human Bradykinin B1 Receptor and Human B2 Receptor InVitro Binding Assay Supporting Methods

Preparation of membranes expressing human B1 and human B2 bradykininreceptor. Membranes were prepared from CHO-d⁻AQN cells stablytransfected with human bradykinin B1 receptor cDNA. For large-scaleproduction of membranes, cells were grown in 100 L suspension culture to1.0E8 cells/mL then harvested using the Viafuge at continuouscentrifugation of 1000g. For pilot studies, cells were grown in 2 Lspinner culture and harvested by centrifugation (1900 g, 10 min, 4° C.).The cell pellet was washed with PBS, centrifuged (1900 g, 10 min, 4°C.), then the cells resuspended in lysis buffer (25 mM HEPES, pH 7.4, 5mM EDTA, 5 mM EGTA, 3 mM MgCl₂, 10% (w/v) sucrose, Complete ProteaseInhibitor tablets (EDTA-free)) to a density of 14% w/v for passagethrough a microfluidizer (Microfluidics 110S, 3 passes, 6,000 psi). Theresulting cell lysate was centrifuged (1900 g, 10 min, 4° C.), and thecrude particulate fraction isolated by centrifugation (142,000g, 1 h, 4°C.) of the low-speed supernatant. The resulting pellet was resuspendedin ⅓ the original lysis buffer volume, homogenized, and recentrifuged asabove. The membrane pellet was resuspended by homogenization in storagebuffer (25 mM HEPES, pH 7.4, 3 mM MgCl₂, 10% (w/v) sucrose and CompleteProtease Inhibitor tablets (EDTA-free)). Single-use aliquots were madeand flash-frozen in liquid N₂ prior to storage at −80° C. Membranescontaining human bradykinin B2R were purchased from Receptor Biology(now Perkin Elmer Life Sciences). They were derived from a CHO-K1 linestably expressing the human B2 receptor developed by Receptor Biologyand subsequently purchased by Amgen. For some studies, membranes wereprepared in-house from this same cell line using the method describedfor human B1 receptor membranes, except cells were grown in rollerbottles and harvested using Cellmate.Radioligand Binding Assay for human B1 and human B2 bradykinin receptor.Human B1 receptor binding assay was performed in 96-well polypropyleneplates (Costar 3365) by adding 50 μL [³H] des-arg¹⁰ kallidin (NET1064;Perkin Elmer Life Sciences) to 10 μL test compound diluted in 90 μlassay buffer (24 mM TES, pH 6.8, 1 mM 1,10 o-phenanthroline, 0.3% BSA,0.5 mM Pefabloc SC, 2 μg/ml aprotinin, 5 μg/mL leupeptin, and 0.7 μg/mLpepstatin A). Membranes (50 μL) were added last. [³H] des-arg¹⁰ kallidinwas diluted from stock into assay buffer to yield a final concentrationof ˜0.3 nM in the assay but was adjusted as needed to ensure aconcentration at or below the K_(d) determined for each batch ofreceptor membranes. Nonspecific binding was defined with 2 μMdes-Arg¹⁰Leu⁹ kallidin. Membranes were diluted in assay buffer to yielda final concentration of 0.068 nM hB1 receptor in the assay. Compoundswere solubilized in either DMSO or ddH₂O, plated into polypropyleneplates (Costar 3365), then serially diluted in either DMSO or dilutionbuffer (20 mM Hepes, pH 7.6, 0.1% BSA) to yield a final concentration ofeither 5% DMSO or no DMSO in the assay. The assay mixture was incubatedwith shaking for 1 hr at RT and then filtered through GF/C platespresoaked in 0.5% polyethyleneimine (Unifilter; Perkin Elmer LifeSciences) using a Filtermate 96-well harvester (Perkin Elmer LifeSciences). Filter plates were rapidly washed 6 times with 200 μlice-cold buffer (50 mM Tris, pH 7.4), dried in a vacuum oven at 55C for15-20 min, backed, and 40 μL per well of Microscint 20 was added. Theplates were sealed and activity read on Topcount (Perkin Elmer LifeSciences) using a count time of 3 min per channel.For human B2 bradykinin receptor, the same procedure was followed withthe following exceptions: [³H] bradykinin (NET706; Perkin Elmer LifeSciences) was used at a final concentration of ˜0.2 nM and non specificbinding was defined with 2 μM bradykinin. Human B2 receptorconcentration was 0.068 nM final in the assay.Data analysis. Data was analyzed in XLFit with the four-parameterlogistic y=A+((B−A)/(1+((C/x)̂D))) and fit with the Levenburg-Marquardtalgorithm. Raw cpm were converted to percent of control values prior toanalysis (POC=((compound cpm−nonspecfic cpm)/(no−compoundcpm−nonspecific cpm)*100)). K_(i) values were determined from the IC₅₀using the Cheng-Prusoff equation and K_(d) values determined by directsaturation binding of the radioligands.The compounds of examples 1, 1a, 1d-1f, 1 h, 3, 3b-3f, 3h-3j, 3l, 4a,5a, 8, 13, and 15, have binding Ki's to the hB1 receptor at a levelbelow 100 nm.

In Vitro B1-Inhibition Activity

A. In Vitro Assay of Human B1 Receptor Function Using Calcium Flux:

Activation of the G_(q) linked B1 receptor results in an increase inintracellular calcium. The calcium sensitive photoprotein aequorin can,therefore, be used as an indicator of B1 receptor activation. Aequorinis a 21-kDa photoprotein that forms a bioluminescent complex when linkedto the chromophore cofactor coelenterazine. Following the binding ofcalcium to this complex, an oxidation reaction of coelenterazine resultsin the production of apoaequorin, coelenteramide, CO₂, and light thatcan be detected by conventional luminometry.

A stable CHO D-/hB1/Aequorin cell line was established and the cellswere maintained in suspension in spinner bottles containing a 1:1 ratioof DMEM and HAM F12 (Gibco 11765-047), high glucose (Gibco 11965-084),10% Heat Inactivated Dialyzed serum (Gibco 26300-061), 1× Non-EssentialAmino Acids (Gibco 11140-050), 1× Glutamine-Pen-Strep (Gibco 10378-016),and Hygromycin, 300 μg/mL (Roche 843555). 15-24 h prior to theluminometer assay, 25,000 cells/well (2.5E6 cells/10 mL/plate) wereplated in 96-well black-sided clear bottom assay plates (Costar #3904).

Media was removed from the wells and replaced with 60 μl of serum freeHAM's F12 with 30 mM HEPES (pH 7.5) and 15 μM coelenterazine(Coelenterazine h Luciferin #90608 from Assay Designs). The plates wereincubated for 1.5-2 h. Ten point IC₅₀ compound plates containing 1:3 or1:5 dilutions of antagonist compounds and an agonist activator plate (20nM des-Arg10-Kallidin final concentration, EC₈₀) were prepared usingHam's F12 with 30 mM HEPES, pH 7.5. Following coelenterazine incubation,an automated flash-luminometer platform was used to dispense the B1antagonist compounds (dissolved in DMSO and diluted with buffer to thedesired concentration (final DMSO concentration <1% DMSO)) to the cellplate, a CCD camera situated underneath the cell plate took 12 images ofthe cell plate at 5 second intervals to determine if there was anyagonist activity with the compounds. The hB1 agonist,des-Arg₁₀-Kallidin, was added to the cell plate and another 12 imageswere recorded to determine the IC₅₀ of the antagonist(s).

The cells were cultured in T225 flask containingHam's F12 Nutrient Mixture (Invitrogen Corp., Cat # 11765-047), 10%Fetal Clone II Bovine Serum (HyClone, Cat # SH3006603), 1 mM Sodiumpyruvate (100 mM stock, Invitrogen Corp., Cat# 12454-013), and 0.4 mg/mLGeneticin (G418; 50 mg/mL active geneticin, Invitrogen, Cat# 10131-207).Culture medium was changed every other day. 24 h prior to the FLIPRassay, the hB2/CHO cells were washed once with PBS (Invitrogen, Cat.#)and 10 mL of Versene (1:5000, Invitrogen, Cat# 15040-066) was added toeach flask. After 5 min incubation at 37° C., Versene was removed andcells were detached from the flask and resuspended in culture medium.Cells were counted and 25,000 cells/well were plated in 96-wellblack-sided clear bottom assay plates (Costar #3904). Cells wereincubated in a 37° C. CO₂ incubator overnight.

The media was aspirated from the cells and replaced with 65 μL ofdye-loading buffer. The loading buffer was prepared by diluting a stocksolution of 0.5 mM Fluo-4 AM (Molecular Probes, dissolved in DMSOcontaining 10% [w/v] pluronic acid) to a concentration of 1 μM in ClearDulbecco's Modified Eagle Medium (DMEM) containing 0.1% BSA, 20 mMHEPES, and 2.5 mM probenecid. The cells were dye-loaded for 1 h at RT.The excess dye was removed by washing the cells 2× with assay buffer.The assay buffer consists of Hank's Balanced Salt Solution (HBSS)containing 20 mM HEPES, 0.1% BSA, and 2.5 mM probenecid. After the washcycles, a volume of 100 μL was left in each well, and the plate wasready to be assayed in the FLIPR System. Single point (10 μM finalconcentration) POC antagonist compound plates or ten point IC₅₀ compoundplates containing 1:3 or 1:5 dilutions of antagonist compounds(dissolved in DMSO and diluted with buffer to the desired concentration(final DMSO concentration <1% DMSO)) and an agonist activator plate (0.3nM bradykinin final concentration, EC₈₀) were prepared using assaybuffer. The cell plate and the compound plates were loaded onto theFLIPR and during the assay, fluorescence readings are takensimultaneously from all 96 wells of the cell plate. Ten 1-secondreadings were taken to establish a stable baseline for each well, then25 μL from the B1 antagonist plate was rapidly (50 μL/sec.) added. Thefluorescence signal was measured in 1-second (1 min) followed by6-second (2 min) intervals for a total of 3 min to determine if there isany agonist activity with the compounds. The B2 agonist, bradykinin, wasadded to the cell plate and another 3 min were recorded to determine thepercent inhibition at 10 μM (POC plates) or the IC₅₀ of the antagonist.

These studies established the antagonist activity of several compoundsat the bradykinin B1 receptors in in vitro cell-based and isolated organassays.

1. Rabbit endothelial cell B1-specific PGI₂ secretion Assay

2. B1 and B2 umblical vein Assay

D. In Vitro B1-Inhibition Activity

The effectiveness of the compounds as inhibitors of B1 activity (i.e.,B1 “neutralization”) can be evaluated by measuring the ability of eachcompound to block B1 stimulated CGRP and substance P release and calciumsignaling in Dorsal Root Ganglion (DRG) neuronal cultures.

Dorsal Root Ganglion Neuronal Cultures. Dorsal root ganglia aredissected one by one under aseptic conditions from all spinal segmentsof embryonic 19-day old (E19) rats that are surgically removed from theuterus of timed-pregnant, terminally anesthetized Sprague-Dawley rats(Charles River, Wilmington, Mass.). DRG are collected in ice-cold L-15media (GibcoBRL, Grand Island, N.Y.) containing 5% heat inactivatedhorse serum (GibcoBRL), and any loose connective tissue and bloodvessels are removed. The DRG are rinsed twice in Ca²⁺- and Mg²⁺-freeDulbecco's phosphate buffered saline (DPBS), pH 7.4 (GibcoBRL). The DRGare dissociated into single cell suspension using a papain dissociationsystem (Worthington Biochemical Corp., Freehold, N.J.). Briefly, DRG areincubated in a digestion solution containing 20 U/mL of papain inEarle's Balanced Salt Solution (EBSS) at 37° C. for fifty minutes. Cellsare dissociated by trituration through fire-polished Pasteur pipettes ina dissociation medium consisting of MEM/Ham's F12, 1:1, 1 mg/mLovomucoid inhibitor and 1 mg/mL ovalbumin, and 0.005% deoxyribonucleaseI (DNase). The dissociated cells are pelleted at 200×g for five min andre-suspended in EBSS containing 1 mg/mL ovomucoid inhibitor, 1 mg/mLovalbumin and 0.005% DNase. Cell suspension is centrifuged through agradient solution containing 10 mg/mL ovomucoid inhibitor, 10 mg/mlovalbumin at 200×g for six min to remove cell debris, then filteredthrough a 88 μM nylon mesh (Fisher Scientific, Pittsburgh, Pa.) toremove any clumps. Cell number is determined with a hemocytometer, andcells are seeded into poly-ornithine 100 μg/mL (Sigma, St. Louis, Mo.)and mouse 1 aminin 1 μg/mL (GibcoBRL)-coated 96-well plates at 10×10³cells/well in complete medium. The complete medium consists of minimalessential medium (MEM) and Ham's F12, 1:1, penicillin (100 U/ml),streptomycin (100 μg/mL), and 10% heat inactivated horse serum(GibcoBRL). The cultures are kept at 37° C., 5% CO₂ and 100% humidity.For controlling the growth of non-neuronal cells,5-fluoro-2′-deoxyuridine (75 μM) and uridine (180 μM) are included inthe medium.2 h after plating, cells are treated with recombinant human β-B1 orrecombinant rat β-B1 at a concentration of 10 ng/mL (0.38 nM). Positivecontrols comprising serial-diluted anti-B1 antibody (R&D Systems,Minneapolis, Minn.) are applied to each culture plate. Compounds areadded at ten concentrations using 3.16-fold serial dilutions. Allsamples are diluted in complete medium before being added to thecultures. Incubation time is generally around 40 h prior to measurementof VR1 expression.Measurement of VR1Expression in DRG Neurons. Cultures are fixed with 4%paraformaldehyde in Hanks' balanced salt solution for 15 min, blockedwith Superblock (Pierce, Rockford, Ill.), and permeabilized with 0.25%Nonidet P-40 (Sigma) in Tris.HCl (Sigma)-buffered saline (TBS) for 1 hat RT. Cultures are rinsed once with TBS containing 0.1% Tween 20(Sigma) and incubated with rabbit anti-VR1 IgG (prepared at Amgen) for1.5 h at RT, followed by incubation of Eu-labeled anti-rabbit secondantibody (Wallac Oy, Turku, Finland) for 1 h at RT. Washes with TBS (3×5min with slow shaking) are applied after each antibody incubation.Enhance solution (150 μL/well, Wallac Oy) is added to the cultures. Thefluorescence signal is measured in a time-resolved fluorometer (WallacOy). VR1 expression in samples treated with the compounds is determinedby comparing to a standard curve of B1 titration from 0-1000 ng/mL.Percent inhibition (compared to maximum possible inhibition) of B1effect on VR1 expression in DRG neurons is determined by comparing tocontrols that are not B1-treated.

In Vivo Antinociceptive Activity in Rat and Monkey Pain Models

A. Rat Neuropathic Pain Model. Male Sprague-Dawley rats (200g) areanesthetized with isoflurane inhalant anesthesia and the left lumbarspinal nerves at the level of L5 and L6 are tightly ligated (4-0 silksuture) distal to the dorsal root ganglion and prior to entrance intothe sciatic nerve, as first described by Kim and Chung (Kim, S. H.;Chung, J. M. An experimental model for peripheral neuropathy produced bysegmental spinal nerve ligation in the rat. Pain 50:355-363, (1992)).The incisions are closed and the rats are allowed to recover. Thisprocedure results in mechanical (tactile) allodynia in the left hind pawas assessed by recording the pressure at which the affected paw(ipsilateral to the site of nerve injury) was withdrawn from gradedstimuli (von Frey filaments ranging from 4.0 to 148.1 mN) appliedperpendicularly to the plantar surface of the paw (between the footpads)through wire-mesh observation cages. A paw withdrawal threshold (PWT)was determined by sequentially increasing and decreasing the stimulusstrength and analyzing withdrawal data using a Dixon non-parametrictest, as described by Chaplan et al. (Chaplan, S. R.; Bach, F. W.;Pogrel, J. W.; Chung, J. M.; Yaksh, T. L. Quantitative assessment oftactile allodynia in the rat paw. J. Neurosci. Meth, 53:55-63 (1994)).

Normal rats and sham surgery rats (nerves isolated but not ligated)withstand at least 148.1 mN (equivalent to 15 g) of pressure withoutresponding. Spinal nerve ligated rats respond to as little as 4.0 mN(equivalent to 0.41 g) of pressure on the affected paw. Rats areincluded in the study only if they did not exhibit motor dysfunction(e.g., paw dragging or dropping) and their PWT was below 39.2 mN(equivalent to 4.0 g). At least seven days after surgery rats aretreated with compounds (usually a screening dose of 60 mg/kg) or controldiluent (PBS) once by s.c. injection and PWT was determined each daythereafter for 7 days.

B. Rat CFA Inflammatory Pain Model. Male Sprague-Dawley rats (200g) arelightly anesthetized with isoflurane inhalant anesthesia and the lefthindpaw is injected with complete Freund's adjuvant (CFA), 0.15 mL. Thisprocedure results in mechanical (tactile) allodynia in the left hind pawas assessed by recording the pressure at which the affected paw iswithdrawn from graded stimuli (von Frey filaments ranging from 4.0 to148.1 mN) applied perpendicularly to the plantar surface of the paw(between the footpads) through wire-mesh observation cages. PWT isdetermined by sequentially increasing and decreasing the stimulusstrength and analyzing withdrawal data using a Dixon non-parametrictest, as described by Chaplan et al. (1994). Rats are included in thestudy only if they do not exhibit motor dysfunction (e.g., paw draggingor dropping) or broken skin and their PWT is below 39.2 mN (equivalentto 4.0 g). At least seven days after CFA injection rats are treated withcompounds (usually a screening dose of 60 mg/kg) or control solution(PBS) once by s.c. injection and PWT is determined each day thereafterfor 7 days. Average paw withdrawal threshold (PWT) is converted topercent of maximum possible effect (% MPE) using the following formula:% MPE=100*(PWT of treated rats−PWT of control rats)/(15-PWT of controlrats). Thus, the cutoff value of 15g (148.1 mN) is equivalent to 100% ofthe MPE and the control response is equivalent to 0% MPE.

At the screening dose of 60 mg/kg, compounds in vehicle are expected toproduce an antinociceptive effect with a PD relationship.

B. Green Monkey LPS Inflammation Model. The effectiveness of thecompounds as inhibitors of B1 activity are evaluated in Male greenmonkeys (Cercopithaecus aethiops St Kitts) challenged locally with B1agonists essentially as described by deBlois and Horlick (BritishJournal of Pharmacology. 132:327-335 (2002), which is herebyincorporated by reference in its entirety).

In order to determine whether compounds of the present invention inhibitB1 induced oedema the studies described below are conducted on malegreen monkeys (Cercopithaecus aethiops St Kitts) at the CaribbeanPrimates Ltd. experimental farm (St Kitts, West Indies). Procedures arereviewed and accepted by the Animal Care Committees of the CR—CHUM(Montreal, Canada) and of Caribbean Primates Ltd. (St Kitts, WestIndies). Animals weighing 6.0±0.5 kg (n=67) were anaesthetized (50 mgketamine kg-1) and pretreated with a single intravenous injection of LPS(90 μg kg⁻¹) or saline (1 ml) via the saphenous vein.

1. Inflammation Studies

Kinin-induced oedema is evaluated by the ventral skin fold assay(Sciberras et al., 1987). Briefly, anaesthetized monkeys were injectedwith captopril (1 mg kg⁻¹ 30 min before assay). A single subcutaneousinjection of dKD, BK or the vehicle (2 mM amastatin in 100 μL Ringer'slactate) is given in the ventral area and the increase in thickness ofskin folds is monitored for 30-45 min using a calibrated caliper. Theresults are expressed as the difference between the skin fold thicknessbefore and after the subcutaneous injection. Captopril and amastatin areused to reduce degradation of kinins at the carboxyl- andamino-terminus, respectively.

Antagonist Schild Analysis

The dose-response relationship for dKD (1-100 nmol)-induced oedema isdetermined at 24 h post-LPS in the absence or presence of differentconcentrations of antagonist. BK (30 nmol) is used as a positivecontrol.

Antagonist Time Course

The time course of inhibition by antagonist is determined at 4, 24 and48 h, 72 and/or 96 h after single bolus administration. BK (30 nmol) isused as a positive control.

Drugs

Ketamine hydrochloride, LPS, amastatin and captopril are from Sigma (MO,U.S.A.). All peptides are from Phoenix Pharmaceuticals (CA, U.S.A.).

Statistics

Values are presented as mean±standard error of the mean (s.e. mean). Inedema studies, the pre-injection thickness of the skin folds wassubtracted from the values after subcutaneous challenge. Curve fittingand EC₅₀ calculations were obtained using the Delta Graph 4.0 softwarefor Apple Computers. Data were compared by two-way analysis of variancefollowed by unpaired, one tail Student's t-test with Bonferronicorrection. P<0.05 was considered statistically significant.

For oral administration, the pharmaceutical composition may be in theform of, for example, a tablet, capsule, suspension or liquid. Thepharmaceutical composition is preferably made in the form of a dosageunit containing a particular amount of the active ingredient. Examplesof such dosage units are tablets or capsules. For example, these maycontain an amount of active ingredient from about 1 to 2000 mg,preferably from about 1 to 500 mg or 5 to 1000 mg. A suitable daily dosefor a human or other mammal may vary widely depending on the conditionof the patient and other factors, but, once again, can be determinedusing routine methods.

The amount of compounds which are administered and the dosage regimenfor treating a disease condition with the compounds and/or compositionsof this invention depends on a variety of factors, including the age,weight, sex and medical condition of the subject, the type of disease,the severity of the disease, the route and frequency of administration,and the particular compound employed. Thus, the dosage regimen may varywidely, but can be determined routinely using standard methods. A dailydose of about 0.01 to 500 mg/kg, preferably between about 0.1 and about50 mg/kg, and more preferably about 0.1 and about 20 mg/kg body weightmay be appropriate. The daily dose can be administered in one to fourdoses per day.

For therapeutic purposes, the active compounds of this invention areordinarily combined with one or more adjuvants appropriate to theindicated route of administration. If administered per os, the compoundsmay be admixed with lactose, sucrose, starch powder, cellulose esters ofalkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesiumstearate, magnesium oxide, sodium and calcium salts of phosphoric andsulfuric acids, gelatin, acacia gum, sodium alginate,polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted orencapsulated for convenient administration. Such capsules or tablets maycontain a controlled-release formulation as may be provided in adispersion of active compound in hydroxypropylmethyl cellulose.

In the case of psoriasis and other skin conditions, it may be preferableto apply a topical preparation of compounds of this invention to theaffected area two to four times a day.

Formulations suitable for topical administration include liquid orsemi-liquid preparations suitable for penetration through the skin(e.g., liniments, lotions, ointments, creams, or pastes) and dropssuitable for administration to the eye, ear, or nose. A suitable topicaldose of active ingredient of a compound of the invention is 0.1 mg to150 mg administered one to four, preferably one or two times daily. Fortopical administration, the active ingredient may comprise from 0.001%to 10% w/w, e.g., from 1% to 2% by weight of the formulation, althoughit may comprise as much as 10% w/w, but preferably not more than 5% w/w,and more preferably from 0.1% to 1% of the formulation.

When formulated in an ointment, the active ingredients may be employedwith either paraffinic or a water-miscible ointment base. Alternatively,the active ingredients may be formulated in a cream with an oil-in-watercream base. If desired, the aqueous phase of the cream base may include,for example at least 30% w/w of a polyhydric alcohol such as propyleneglycol, butane-1,3-diol, mannitol, sorbitol, glycerol, polyethyleneglycol and mixtures thereof. The topical formulation may desirablyinclude a compound which enhances absorption or penetration of theactive ingredient through the skin or other affected areas. Examples ofsuch dermal penetration enhancers include DMSO and related analogs.

The compounds of this invention can also be administered by atransdermal device. Preferably transdermal administration will beaccomplished using a patch either of the reservoir and porous membranetype or of a solid matrix variety. In either case, the active agent isdelivered continuously from the reservoir or microcapsules through amembrane into the active agent permeable adhesive, which is in contactwith the skin or mucosa of the recipient. If the active agent isabsorbed through the skin, a controlled and predetermined flow of theactive agent is administered to the recipient. In the case ofmicrocapsules, the encapsulating agent may also function as themembrane.

The oily phase of the emulsions of this invention may be constitutedfrom known ingredients in a known manner. While the phase may comprisemerely an emulsifier, it may comprise a mixture of at least oneemulsifier with a fat or an oil or with both a fat and an oil.Preferably, a hydrophilic emulsifier is included together with alipophilic emulsifier which acts as a stabilizer. It is also preferredto include both an oil and a fat. Together, the emulsifier(s) with orwithout stabilizer(s) make-up the so-called emulsifying wax, and the waxtogether with the oil and fat make up the so-called emulsifying ointmentbase which forms the oily dispersed phase of the cream formulations.Emulsifiers and emulsion stabilizers suitable for use in the formulationof the present invention include Tween 60, Span 80, cetostearyl alcohol,myristyl alcohol, glyceryl monostearate, sodium lauryl sulfate, glyceryldistearate alone or with a wax, or other materials well known in theart.

The choice of suitable oils or fats for the formulation is based onachieving the desired cosmetic properties, since the solubility of theactive compound in most oils likely to be used in pharmaceuticalemulsion formulations is very low. Thus, the cream should preferably bea non-greasy, non-staining and washable product with suitableconsistency to avoid leakage from tubes or other containers. Straight orbranched chain, mono- or dibasic alkyl esters such as di-isoadipate,isocetyl stearate, propylene glycol diester of coconut fatty acids,isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate,2-ethylhexyl palmitate or a blend of branched chain esters may be used.These may be used alone or in combination depending on the propertiesrequired. Alternatively, high melting point lipids such as white softparaffin and/or liquid paraffin or other mineral oils can be used.

Formulations suitable for topical administration to the eye also includeeye drops wherein the active ingredients are dissolved or suspended insuitable carrier, especially an aqueous solvent for the activeingredients. The active ingredients are preferably present in suchformulations in a concentration of 0.5 to 20%, advantageously 0.5 to 10%and particularly about 1.5% w/w.

Formulations for parenteral administration may be in the form of aqueousor non-aqueous isotonic sterile injection solutions or suspensions.These solutions and suspensions may be prepared from sterile powders orgranules using one or more of the carriers or diluents mentioned for usein the formulations for oral administration or by using other suitabledispersing or wetting agents and suspending agents. The compounds may bedissolved in water, polyethylene glycol, propylene glycol, ethanol, cornoil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodiumchloride, tragacanth gum, and/or various buffers. Other adjuvants andmodes of administration are well and widely known in the pharmaceuticalart. The active ingredient may also be administered by injection as acomposition with suitable carriers including saline, dextrose, or water,or with cyclodextrin (i.e. Captisol), cosolvent solubilization (i.e.propylene glycol) or micellar solubilization (i.e. Tween 80).

The sterile injectable preparation may also be a sterile injectablesolution or suspension in a non-toxic parenterally acceptable diluent orsolvent, for example as a solution in 1,3-butanediol. Among theacceptable vehicles and solvents that may be employed are water,Ringer's solution, and isotonic sodium chloride solution. In addition,sterile, fixed oils are conventionally employed as a solvent orsuspending medium. For this purpose any bland fixed oil may be employed,including synthetic mono- or diglycerides. In addition, fatty acids suchas oleic acid find use in the preparation of injectables.

For pulmonary administration, the pharmaceutical composition may beadministered in the form of an aerosol or with an inhaler including drypowder aerosol.

Suppositories for rectal administration of the drug can be prepared bymixing the drug with a suitable non-irritating excipient such as cocoabutter and polyethylene glycols that are solid at ordinary temperaturesbut liquid at the rectal temperature and will therefore melt in therectum and release the drug.

The pharmaceutical compositions may be subjected to conventionalpharmaceutical operations such as sterilization and/or may containconventional adjuvants, such as preservatives, stabilizers, wettingagents, emulsifiers, buffers etc. Tablets and pills can additionally beprepared with enteric coatings. Such compositions may also compriseadjuvants, such as wetting, sweetening, flavoring, and perfuming agents.
